I have just completed a small piece of work as follows.
1. Turned off boiler
2. Turned off gas
3. Turned off mains
4. Drained down system
5. Addded a new radiator to the system
6. Turned on mains
7. Topped up system (and bled radiators) to 1.25 bar.
I left the system without gas, with eletric turned off, and mains turned off overnight. I have just checked and seen that the pressure is 1 bar.
This has happened two nights in a row.
There does not appear to be any leaks anywhere (floorboards are currently up, and the new radiator I installed seems sound).
Does anyone know what the problem might be?
